  • Patent number: 7059020
    Abstract: The invention concerns a hinge for doors and similar construction components. The hinge can be installed in a recess of a door frame, whereby the recess receives the hinge completely when the door is closed. In this way, the hinge will be completely invisible when the door is closed, and also inaccessible from the outside. This means that the hinge offers increased resistance against break-ins as well as an improved aesthetic appearance. In order to minimize the size of the required recess, the hinge flap that is nearest to the door frame incorporates a flat-angled curved profile, while the hinge flap (3) that is nearest to the door has a profile that encloses the hinge axis (4).

  • Publication number: 20040205932
    Abstract: The invention concerns a hinge for doors and similar construction components. The hinge (1) can be installed in a recess (27) of the door frame (28), whereby the same receives the hinge (1) completely when the door is closed. In this way the hinge will be completely invisible when the door is closed, and also inaccessible from the outside. This means that the said hinge offers increased resistance against break-ins as well as an improved aesthetic appearance. In order to minimise the size of the required recess the hinge flap (2) that is nearest to the door frame incorporates a flat-angled curved profile, whilst the hinge flap (3) that is nearest to the door is equipped with a profile encloses the hinge axis (4).

  • Publication number: 20010025396
    Abstract: The invention relates to a hinge, in particular for doors, windows or the like, with two hinge wings (1, 2) which can be fastened on a hinge bearer (11 or 12), wherein at least one hinge wing (1) is adjustable transversely to its installation plane (17) through two setting screws (21a, 21b) disposed offset in height, which can be screwed into the hinge bearer (11) of the hinge wing (1) transversely to its installation plane (17). By actuating the setting screws (21a, 21b) it is possible to adjust the premounted hinge readily and finely into a precisely vertical installation position.

  • Patent number: 6202255
    Abstract: The invention relates to a hinge, in particular for doors, windows and the like, whose hinge wings (1,2), each fastenable on one hinge holder (13, 14), are pivotable relative to one another about an axis of hinge rotation, with at least one of the hinge wings being provided with an adjustment device for adjusting the hinge wing transversely to the axis of hinge rotation. In order to facilitate the adjustability after installation, the adjustment device is formed as an adjusting pin (15) disposed transversely to the axis of hinge rotation (3). Pin ends (15a, 15b) of the pin (15) are disposed eccentrically with respect to one another and, after installation, are rotatably supported in receiving bores (16, 17) of the hinge wing (1) or of the hinge holder (13) associated with it.
